SAWYER: Can't say I blame poor Kato. His lady speaks English all this time, and he didn't have a clue? I'm surprised he didn't try to swim out of here.

SAWYER: How'd it happen?

KATE: Locke said that, uh, he fell off a cliff while they were out hunting boar.

SAWYER: The boar they never seem to get.

SARAH: A little over two years ago, I blew a tire out, flipped over the center divider into oncoming traffic and was hit head-on by an S.U.V. My back was broken. They all said it was irreparable. And then there was Jack. And he promised that he would fix me because that's the kind of guy he is. Because you are the most committed man I have ever known. Because you fixed me, I will dance at our wedding. To Jack. My hero, Jack.

JACK: Veins are like a wet noodle. First you have to find one, then you have to have a hollow needle sharp enough to actually pierce it. I've got bamboo.

JACK: So you only asked four people?

CHARLIE: I asked the whole sodding camp. No one knows their blood type. I don't know my bloody blood type.

JACK: O-Neg is the universal donor. It's in the ballpark; it's not a match. My blood could put him into anaphylactic shock -- stop his heart.

JACK: Tell Kate to wait until the contractions are sixty seconds apart. You got that? Now, she's gonna need to make sure that Claire pushes, but not too hard, not too fast -- just until the head is clear, and then as hard as she can. Now, when the baby is out, make sure she clears its nose and its mouth.

CHARLIE: Okay, but you'll be there by then, right?

JACK: No, I won't.

CHARLIE: Jack--

JACK: I'm not going anywhere. I need to stay here. Now you tell Kate that she's gonna have to deliver this baby.

SUN: It's not working.

JACK: Blood's not the problem. It's the leg. All the blood's pooling there. Compartment syndrome. He didn't get this injury from a fall. Something crushed his leg. What are you doing?

SUN: You've given him enough.

CHRISTIAN SHEPHARD: Sarah is a beautiful girl.

JACK: Hell yeah, she is.

CHRISTIAN SHEPHARD: You love her?

JACK: Absolutely.

CHRISTIAN SHEPHARD: Then why are you sitting out here?

JACK: What if I can't be the husband or the -- or the father that I want to be? What if I asked her because -- because I saved her life? Should I marry her, Dad?

CHRISTIAN SHEPHARD: Commitment is what makes you tick, Jack. The problem is you're just not good at letting go.

JACK: We can't use the axe.

SUN: What are you doing?

JACK: His right leg is filling with blood. If I don't stop it, I won't be able to save him.

SUN: You don't mean that --

JACK: The leg is dead. There's no other choice.

JACK: I didn't write any vows. I've been trying to for a month, but ... I couldn't, and ... so I started to wonder why that was. And as time went on, it only got worse, because I'm -- because I'm not good at letting go. Or maybe I'm afraid of what'll happen if I fail. But I know one thing. I would have never been able to write anything as beautiful as what you just said. And last night, Sarah, when you were talking about the accident, you got it all wrong. I didn't fix you. You fixed me. I love you, Sarah, and I always will.
